SPECIFICATION forming part of Letters Patent No. 763,391, dated June 28,1904 i Application filed March 22,1904. smart. 199,412. (No model.)

To all whmn it 'may concern:

Be it known that we, PETER C. HAINS, residing at IVashington, in theDistrict of Columbia, and CHARLEs R. WEAVER, residing at Baltimore.- inthe State of Maryland, citizens of theUnited States, have inventedcertain new and useful Improvements in Lifting- Buckets, of which thefollowing is a specification. I s

The invention to be hereinafter described relates to buckets whereby notonly can concrete be transported while in a plastic condition, but theingredients composing the concrete can be intimately mixed anddischarged either directly in place or into a similar bucket, wherebyfurther mixing may be assured;

As pointed out in Letters Patent N o. 633, 312, granted'to Peter C.Hains, J r., and Charles R. Weaver, dated September 19, 1899, anexcellent quality of concrete can be made by arranging the cement, sand,and stone in layers in a suitable receptacle, wetting the coarseringredients, and then discharging the mass from the bottom of thereceptacle, so that the wet coarse material in falling is brought incontact with the cement and sand and becomes thoroughly covered. Incarrying out the process set forth in said Letters Patent, however, ithas been necessary to elevate the separate materials, and in devisingthe present character of bucket due consideration has been given thesematters. It is also found in the practical placement of concrete that attimes and no more, and it'is likewise an important;

consideration that such mixing or handling" only a portion of the entirecontents of-the bucketfis desired to complete a particular piece of workand that means should be available to permitthe discharge of the desiredquantity ing and handling bucket having a contracted bottom dischargecontrollable as to the quantity of concrete that may be permitted topass and so shaped and braced by supporting-legs that it shall be ofsimple construction, yet suf- Y ficiently strong and unyielding incharacter to of the bucket, showing the discharging-doors closed. Fig. 2is a similar side elevation of the bucket at right angles to the viewshown in Fig. 1; Fig. 3 is a plan view showing the supporting andstrengthening brackets, doors, handles, and braces in dotted lines; andFig. 4: is a view similar to Fig. 1, showing a slightlymodified form ofreceptacle, but essentially similar to those of Figs. 1 and 2.

The bucket comprises a receptacle (designated generally by A) which maybe made of any suitable material, having downwardlyconverging walls a,forming an inverted truncated cone, and provided at the bottom with acontracted discharge-opening a, through which the concrete may bedischarged more or less slowly in contradistinction to a sudden bulkdischarge which takes place, when, as in a cylindrical bucket with aswinging door, the entire contents of the bucket are permitted to fallsimultaneously. Preferably the upper portion of the inclined part (6 ofthe receptacle may be provided with a short bracingring 64 of metal,surmounted by a strengthened band (0 the said parts being properlyriveted together, as shown in the drawings. Secured to the inclinedexterior walls of the receptacle are the brackets B and B, which may beof any suitable construction and of desired number, so as to form bothvertical and horizontal supports for the inclined walls of thereceptacle, as hereinafter more fully described. As shown in thedrawings and as one embodiment of the invention, the brackets B B areformed of angle-iron having the vertical supporting portions 61) and thehorizontal strengthening portions 5 Z2 respectively, the ends of whichvertical and horizontal portions are preferably joined by adiagonalstrengthening rib or flange Z). The Vertical supporting portions I) ofthe oppositely disposed brackets B, Fig. 2, extend downward from theinclined walls of the receptacle below the bottom discharge-opening a,and the lower surface of the horizontal strengthening portions 7f of thebrackets B are thus disposed below the opening a, the ends of thevertical supporting and horizontal strengthening portions 5 and b ofbrackets B, as shown in Fig. 2, being secured to the inclined walls ofthe receptacle and connected by the diagonal flange or rib If, alsosecured to the inclined walls.

The brackets B, arranged on diametrically opposite sides of the bucketat right angles to the brackets B, have their vertical supportingportions bextended downward a less distance than the vertical supportingportions 5 of the brackets B, so that the lower surface of thehorizontal strengthening portions 6 of the brackets B are disposed abovethe bottom opening a for a purpose as will presently appear. In otherrespects the vertical supporting and horizontal strengthening portions 6b of brackets B are formed and secured together and to the inclinedwalls of the receptacle a substantially in the same manner as describedfor the brackets B.

The brackets B each have secured thereto a projecting foot 0, preferablyin prolongation of the vertical supporting portion Z) and extended belowthe horizontal strengthening portions 6 so that they and the horizontalstrengthening portions 6 of the brackets B form a support for the bucketwhile resting upon the ground, the bottom opening a in this positionbeing supported some distance above the ground. The contracteddischargeopening a is preferably closed by a sliding door, which may beformed of two parts, as indicated in the drawings at (Z (Z, and each ofsaid portions (Z (Z of the door is carried by an arm d, pivoted at (Z toone of the brackets .B, their opposite ends being prolonged to formhandles (Z by which the doors may be operated. Connecting the brackets BB with one of the brackets B are the braces e, as more clearly shown inFigs. 1 and 3, and thesebraces provide a supporting means upon which thehandles (Z of the door-operating means may slide during their openingand closing movements, suitable stops 0 being provided on the braces cto regulate the extent of opening movement of the doors d d. Similarstops maybe secured to the brackets B to limit the doors in theirclosing movement; but, as will be understood, of course, these and thestops (3 are not essential, they being merely convenient means forregulating the extent of full opening and closing movement of the doors.

Since the doors are slidable over the opening a, it is manifest that thehorizontal strengthening portions 6 of the brackets B would prevent suchsliding movement of the doors if they were disposed below thedoor-opening, as are the horizontal strengthening portions Z3 of thebrackets B; but, as heretofore stated, the horizontal strengtheningportions 5 being disposed above the bottom opening the portions (1 d ofthe door may be moved sidewise by the operating-handles. In thismovement of the doors the handles rest upon the braces e and serve assupports, as well as braces, between the brackets B and B, and the doorsin their opening movement slide beneath the lower surface of thehorizontal strengthening portions 6 of the brackets B, as will beclearly apparent from Fig. 1.

In a device of the character described, intended for the handling andmixing of concrete, it is obvious that the receptacle is subjected tomany vertical and horizontal strains during loading and hoisting, owingto the material contained therein, and the brackets B B serve to impartto the receptacle sufficient horizontal and vertical bracing to obviateany distortion of the bucket in use, and particularly is this the case,since the brackets are secured to the inclined walls of the receptacle.

The bucket is provided with suitable eye or lifting plates F, to whichthe chains F or other lifting means may be attached.

In Fig. 4 we have shown a slightly-modified form of the receptacle,which instead of having its walls of uniform inclination, as shown inFigs. 1, 2, and 3, has the lower part formed with a differentinclination, as shown at H, through which the material passes on its wayout of the receptacle. This portion H may for the purpose ofidentification be designated a deflecting device, since as the materialpassing through the bottom opening slides down the inclined sides of thereceptacle more or less its momentum carries it across the part H, andit strikes the opposite wall thereof, thus being deflected again in anopposite direction, so that when the bucket is used for mixing concretethe heavier and weighty material is more thoroughly brought into contactand coated with the cement. It is not always necessary to use thedeflecting device H, although it is under some conditions desirable.

We have not found it necessary to enlarge upon the method of mixingconcrete by the present form of bucket, as that is fully described andmade clear in the Patent No. 633,312, hereinbefore referred to.

While we have shown and described the particular forms of brackets B Bas composed of angle-iron and having the brace connection with theinclined walls of the receptacle, it is obvious, of course, that otherforms and number of brackets may be employed, the essential being that,of whatever form, they shall be connected to the inclined walls of thereceptacle and have vertical supporting and horizontal strengtheningportions, and while we have shown the door as formed of two parts (Z (Zmovable toward and from each other over the discharge-opening it isobvious, of course, that other forms of sliding doors might be employed,the essential being in this respect that the door be operable so as toregulate the amount of concrete that may be discharged at any one time.1

We have shown the receptacle a in the form of an inverted truncatedcone; but it is obvious, of course, that the inere shape or outline incross-sction may be varied as long as the walls of the receptacle areinclined to converge downwardly.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. A bucket, comprising a substantially conical shaped receptacle,having a bottom discharge-opening, supportingbrackets secured to saidreceptacle and extending below the inclined sides thereof, a slidingdoor for closing said bottom discharge-opening and means for moving saiddoor to permit the discharge of a part or all of the material from saidbucket.
